Bug or not

I update rails from 2.0.2 to 2.2.3, and I start server by ruby
script/server or mongrel_rails. But when I use my system, for test of
view, the system often exit auto and report a failed to allocate memory.
I try to change the enviroment, then I found something. I have installed
ramdisk on my computer, if I remove it, the rails seemed normal, but if
I reinstall the ramdisk, it reopot error and exit often.
It's bug or not?

I would think
that when you have a ramdisk it takes up a lot of your ram and you are
trying to swap pages out and for some reason that is not working.
Maybe you do not have a swap space allocated. You do not say how much
ram you have or how big the ramdisk. I imagine the system increased a
bit in memory requirements from 2.0.2 to 2.2.3 which is instigating
your problem. I would not use ramdisk unless you will have at least 2G
left after running the ramdisk.

YMMV
